Used by only the awesomest of people. Used to describe something amazing or not even explainably unbeleivable.
"dude, we went boardin' today and I landed a jump that was totally insane off the richter scale."

Something that is too extreme to be measured. The Richter Scale is officially used for measuring earthquakes; anything above 7 is described as a major quake. Anything "off the Richter Scale" (or "Off the Richter") is therefore an extreme example.
"Man, that surf was totally off the Richter Scale".
